When Flywheel Backend is set to instancing moving contraptions don't render properly/render with vanilla lighting instead of the shader's lighting. If Flywheel Backend is disabled and shaders disabled and re-enabled then it lights properly but if Flywheel Backend is disabled then the ropes on rope pulleys don't render when moving (Rubidium issue)

Using Complementary Reimagined, oculus-1.4.3a, rubidium-0.5.4 and oculus-flywheel-compat-1.18.2-0.1.8-BETA
